Specification of Letters Patent. Patented Nov. 26, 1912.

Application filed December 14, 1909. Serial No. 533,093.

T 0 all whom it may concern:

Be itknown that I, Ltxnsnnr Sonrmtons.

a citizen of the United States, residing in i Hasbrouck Heights, countyof Bergen, and 1 State of New Jersey, have invented new and usefulImprovements in Lighting-Fixtures, of which the following is adescription.

My invention pertains to that class of lighting fixtures used for thesupport of incandescent lamps and distribution of light given thereby;

My invention has for its particular object to support an electric lampand hold a shade or reflector in proper operative relation thereto insuch manner as to direct the rays in a desired direction.

A further object of my invention is to provide means whereby the shademay be clamped in a given relation with respect to the lamp and heldrigidly in this position and also to be readily removed by propermanipulation when desired. In the drawing Figure I is a vertical sectionand partial elevation of a fixture embodying one form of my invention.Fig. II is avertical section and partial elevation of a fixtureembodying a modified form of my invention. Fig. III is a perspective ofone of theparts of my improved fixture shown in section in Figs. I andII as will hereinafter be more plainly explained.

In Fig. I, 1 represents any suitable type of bracket or other supportprovided with the depending threaded nipple 2 upon which is threaded anornamental bonnet 3 provided at its lower portion with a flange which ispreferably knurled so as to be easilyv turned.

by hand. 5, represents a metal spinning or bonnet free to slide over thethreads of the member 2 and provided at its lower portion a with theconical flange portion 6. 7 is a bonnet-shaped member attached tothemember 2 as indicated and having its lower or body portion formed ofindependent fingers 8 as shown more plainly in perspective in Fig. III.The lower portion of the fingers 8 is so shaped that when pressedinwardly by a downward movement of the conical member 6 of the member 5they will fitinto the flange 9 of the top of the shade 1O intended tobeheld by the fixture as shown in Fig. I. 11 represents the incandescentlamp or bulb supported by the socket. 13 which is screwed into theinternal bore 12 of the bracket or other support 1 through which borethe wires are led to proper connections within the socket 13.

Referring to Fig. II in which like numerals are used to indicate likeparts it will be noted that the device shown in F ig. II is the same asthat shown in Fig. I with the exception that the loose spun bonnetmemher 5 is omitted and the member 3 is so shaped as to have an internalonical bore adapted to press the fingers-8 into the flange 9 of theshade 10 when the bonnet J is moved in a downward direction as by beingscrewed downwardly on the threaded portion 2.

The operation or" my improved invention is substantially as follows:Referring to Fig. I and starting with the shade in place and thevarious parts shown in the position shown in the drawing, if it bedesired to clamp the shade a little more firmly in the fixture. theflange 4 may be turned in such direction that the member 3 will movedownwardly upon the threaded'portion 2 and press the member 5 downwardlyand crowd the flange portion 6 upon the fingers 8 and force the samemore tightly into the flange 9 of the shade 10. If itbe desired toremove the shade the fiange 4 may be grasped and the member 3 rotated soas to move upwardly uponthe threaded portion 2 until the member 5 may beraised so that there will be sufficient room between the fingers 8 andthe inside of the conical portion 6 that the shade may be sprung out ofthe fingers 8 in a well-known manner. The shade may readily be replacedby springing the same in place under the fingers again and then thebonnet 5 may be dropped upon the fingers and if the member 3 be screweddown firmly the shade will be held rigidly in place.

Referring to F II andstarting with the parts in the positions shown inthe drawing, if it be desired to more firmly grip the shade the flange 4may be readily grasped by hand and the member 3 turned in such directionthat it will move downwardly upon the threaded portion 2 and thus owingto the conical shape of its inner surface force the fingers 8 moretightly into the flange 9 of the shade. If, however, it be desired toremove the shade the member 3 may be rotated so as to move upwardly uponthe threaded portion 2 until sufficient clearance is left between thefingers 8 and the interior of the member 3' that the shade 10 may besprung-out in a well-known manner. The

, the member in Fig. I or the member 3 in Fig. II is raised the fingerswill remain in contact with the inner conical surface and simply opensufficiently to release the flange 9 in a well-known manner.

From the foregoing it will be obvious that I have produced a lightingfixture adapted to hold an electric lamp in place and firmly hold ashade in operative relation thereto in such manner that the same willnot rattle when the fixture is subjected to severe vibration as whenused in railway cars. Further, the various parts of my improved fixtureremain at all times in operative relation and no parts have to beremoved during the process of taking out or putting in shades and thusthe danger of loss during this process is avoided.

It will also be noted that my improved fixture is of such type as willpermit of ornamental design inasmuch as the shade engaging parts arepractically concealed by an ornamental bonnet.

.I do not wish in any way to limit myself to the exact constructions ormodes of opera- .tion set forth in the above description for it isobvious that considerable change in the form of fixture may'be madewithout departing from the spirit of my invention which is as set forthin the-following claims:
